B Correct answer
Explanation

The first modern toothbrush with hog hair bristles in ivory handles was invented in China during the Tang Dynasty (around 618-907 AD). This design later evolved and spread to Europe. The natural bristles from hogs or horses were used until nylon bristles were invented in the 20th century.

AI explanation

The commonly cited origin of the modern bristle toothbrush traces back to China (Tang Dynasty era), where bristles from hog or horsehair were fastened into handles carved from bone or bamboo/ivory to clean teeth. This design was later brought to Europe and refined, but the hog/horsehair-and-handle construction described is the Chinese prototype.
